sorry. comment 5
Sorry, missed that. So no, this is not really a duplicated of bug 1206848 because 7efc3b726103 ("mm/compaction: fix set skip in fast_find_migrateblock") is not part of 5.14.21-150400.24.41. So this needs Vlastimil's eyes. You can of course try the newer kernel referenced below just to see whether this is still reproducible but the underlying problem will be certainly different. Vlastimil, could you have a look at the tracing data please? -- You are receiving this mail because: You are on the CC list for the bug.
